Cuisinart DBM-8 coffee grinder

Have you tried checking the output chute at the bottom to see if it is clogged up? I was having low flow issues, which is how I found this post, and went and cleaned it out completely. I was amazed, and a bit disgusted, at how much powder was stuck in there. The top screws off nice and easy. then just use the brush down the chute there and at the front behind where the bin is. I also ran popping corn through it and got out even more. Then I threw all the attachments into the dishwasher, top rack like the manual says.

Hope that helps you.
